DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 382,881, dated May 15, 1888.

Application filed Septemberlii, 1887. Serial No. 249,576., (No model.)

To aZZ whom it may concern:

Be it known that I, SALVIN FREDERICK KED- LOGG, a citizen of the United States, residing at Clay Centre, in the county of Clay and State of Kansas, have invented a new and useful Improvement in Devices for Converting Reciprocating Motion into Rotary Motion, of which the following is a specification.

My invention relates to improvements in dev1ces for converting reciprocating orrectilinear motion into rotary or curvilinear motion; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, which fully illustrate my invention, Figurel is a side elevation of my improved device. Fig. 2 is a similar view looking at the opposite side; and Flg. 3 is a plan View, partly in horizontal section.

Referring to the drawings by letter, A designates a supportingframe, composed of the parallel bars a a, mounted upon suitable rests of any desired construction. At one end of one of the side bars I secure ashort standard, B, which is longitudinally grooved on its inner face, in which groove the reciprocating rod D fits and works. To the inner side of the reciprocating rod D, I secure a yoke, E, in which I pivotally mount a head-block, F.

G designates a rocking lever, which is fulcrumed between the upper ends of two standards, H H, which are mounted upon the side bars, a, of the frame A, and is provided at one end with a fork, I, the arms or tines of which fit upon opposite sides of the head-block F. The opposite end of the lever is provided with a depending link, J, and a similar link, K, depends from the lever G near head-block, both of which will be more fully hereinafter referred.

L M designate two similar cog-wheels, which are mounted upon shafts journaled in the side bars,a a,of the frameA, and thetecth of which mesh, as clearly shown. On one faceeach of these cog-wheels is provided with theinternal ratchet-rim N, and on the shaft of each of the wheels L M, I loosely mount a collar, 0, having the laterally-extending lugs P, in the slotted ends of which I pivotally secure an upwardly-projecting pawl, (,1, which engages the internal ratchet-teeth of the rim N, The lower ends of the links J K are pivoted to these pawls Q, as shown, so that as the lever G oscillates the pawls will be alternately raised and lowered.

R designates a transverse shaft, on which is mounted a pinion, S, meshing with the wheel M,and on one end of the said shaft R, I mount a fly-wheel, T, while on the other end I mount a band-pulley, U, by means of which the motion may be communicated to the machinery to be driven.

The operation of the machine will be readily understood. WVhen the reciprocating rod makes its downward stroke, the near end of the oscillating lever will be carried downward, thereby depressing the pawl connected with said end of the lever. At the same time the opposite end of the lever is elevated, thereby drawing up the pawl connected therewith, which engages the ratchet-rim and thereby rotates the wheel. On the reverse stroke of the reciprocating rod theotherpawl will bebrought into play and the power applied to the other gear-whee],- and as the said wheels are geared together their rotation will be continuous, as will be readily understood.

My device is simple and efficient and its advantages will be readily appreciated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination ofthe supporting-frame, the gear-wheels mounted in said frame and meshing together and provided with internal ratchet rims, the oscillating lever mounted above said wheels, the reciprocatingrod connected to said lever, the pawls loosely mounted on the gearwheel shafts, and the links connecting the opposite ends of the lever with the said pawls, substantially as described.

2. Thecoinbination oft-hesupporting-frame, the cog-wheels mounted thereon and geared together and provided with internal ratchetrims, the standards mounted on the support ing-frame, the oscillating lever fulcrumed between said staudards and forked at one end, the reciprocating rod having a yoke on one side,

the head-block pivotally mounted in said yoke, In testimony that I claim the foregoing as my and to which the tines of the forked end of the own I have hereto affixed my signature in presosoillating lever are fitted, the pawls loosely ence of two witnesses.

mounted on the shafts of the cog-wheels and SALVIN FREDERICK KELLOGG.

5 engaging the ratchet-rims thereof, and the Witnesses:

.links connecting the ends of the lever with O. P. TELLEs,

said pawls, substantially as specified. HENRY HUNSINGER.
